Update libstdc++.so.6.18 -> libstdc++.so.6.20 about steam-runtime HOT 8 OPEN

from steam-runtime.

c++ ABI is hell on earth. The reasonable thing to do is to statically link libstdc++ into the runtime (same thing would apply to libgcc) and let games statically link theirs.
More over, it's compiler/runtime specific. It's so hard to get right, there is near 0 "ok" c++ compiler/runtime for "production".
And look how hard and long it is to code an alternative (clang).
c++ is not something sane.

Well, I'd also be happy if this libstdc++ was removed from Steam runtime but for some reason unknown to me Steam wants to ship it so I'm at requesting that at least a non-obsolete version is shipped.

I think it's a good thing to keep libstdc++ in the runtime. But game devs should be directed to statically link their libstdc++ in their binaries (and libgcc too).
Since gcc 4.7 it's 2 gcc command line options, then super ultra easy to add.
Keeping that lib in the runtime is a kind of guardian against "you don't have the latest c++ ABI/feature on your gnu/linux system then your game won't run". The libc/GL/x11/alsa system libs are already too much and they rely on simple C entry points. Let me guess what will happen on the medium term with a libstdc++ which evolves super fast due to the current c++ standardisation body fenzy. With the insanity of the c++ ABI... it's unreasonnable. Moreover maybe clang c++ ABI will diverge from the gcc c++ ABI (or be just unable to be really compatible since it's hell on earth). BTW, no idea of intel c++ ABI direction.

IMHO, the right way:

• keep the shared libstdc++ into the runtime
• statically link steam client/runtime with libstdc++ (and libgcc)
• direct games devs to statically link their games as much as they can
  But the end decision belongs to valve technical management staff.

@sylware care to say which two command line options? Thanks.

static-libgcc ... there is an application for c++ apps too, like static
libstdc++

@sylware yes, I totally agree games should staticly link against libstdc++.
Please, Valve, make that an official recommendation if not a requirement to all future games. It will save tons of maintenance time.
